SELF-LOCKING oonr. errors. J

Application filed October 12, 1922 Serial No. 594,083.

To all whom it may concern:

Be it known that I, EMIL Gr. BARNEKO, a citizen of the United States, residing at Valparaiso, in the county of Porter and State of Indiana, have invented certain new and useful Improvements in Self-Locking Coal Chutes, of which the following is a specification.

My invention relates to improvements in self-locking coal chutes and it more especially consists of the features hereinafter pointed out in the annexed claims.

The purpose of my invention is to provide a coal chute that is selfcontained and strongly made of sheet metals; that has a one-piece frame formed of steel angles welded together at the corners of the frame; that has inwardly projecting angles secured to the frame along the top and sides forming a stop for the closed door; that provides a sheet metal body on the outside of which there are side angles adapted to hold the coal chute firmly in the building wall; that also provides a siding protector pivoted to the body of the chute adapted to be raised into position by hand where it is held by a spring or other catch on the inside of the to completely hide such means when the door of the chute is closed; that provides means for automatically locking the chute on the inside through the closing of the door; that provides angular reinforcements near the upper and lower edges of the door; that forms the lower edge of the door into'a tube through which the full length steel pivot rod passes; and that provides stops for limiting the open position of the door when it functions as a chute.

With these and other ends in View, I illustrate in the accompanying drawing such instances of adaptation as will disclose the broad underlying features without limiting myself to the specific details shown thereon and described herein.

Figure 1 is an elevation in cross section of the coal chute closed.

Fig.2 is a similar view of the upper portion of the coal chute showing the parts in their open relation.

Fig. 3 is a plan view section.

In practically carrying out my invention, I provide a frame 1 made up of angle steel that is welded at the corners instead of employing cast iron frames as has been the ac tual practice heretofore. On the inslde of of Fig. 1 partly in this frame in line with the inner edge thereof, I securea steel angle of smaller cross section along the-top and the two sides of the frame opening. A sheet steel body 3 having top and bottom and two sides is secured by riveting or otherwise to the frame 1. body portion extends through a corresponding opening in the building wall 24. It has steel angles a riveted to its sides. These angles abut the inside of the wall 2 1 and thus securely hold the coal chute in place because they cooperate with the projecting portion of the frame 1 which abuts the wall of the building on the outside. This construction insures the coal chute retaining its position throughout the most exacting condit-ion of service.

A. door 5 extends from side to side and vertically to fill the opening of the frame 1 and it is stopped from moving too far in- This ward by the steel angles 2. It is reinforced along the top edge by an angle 6 facing outward and an angle 7 near the lower edge also facing outward, as shown in Fig. 1. Below the angle 7 the door 5 formed of steel plate is bent into a tube 8 throughout its entire length. In this tube a pivot or hinge rod 9 is placed. Its ends have bearing in the frame 1 at 25. By rolling the lower edge of the door into a tube 8, the use of all kinds of riveted hinges is eliminated, and an exceedingly strong, simple and efficient structure is secured. The door 5 has angular shaped steel side pieces 10 that are. secured to the door by steel angles 11 placed on the inside of the pieces 10' and riveted or otherwise fastened thereto and the door 5. Along the upper edge of the side pieces 10 reinforcing bars 12 are placed, as shown in Figs. 1 and 3. These bars at their outer end terminate in a projection 13 which serve to hold the door from moving too far downward when it is open for the reception of coal etc. Gravity hooks 15 are pivoted to the sides 10 at 16. Near the pivot'16 they terminate in beveled ends 17. reason of the fact that these ends engage the under side of the bars 12, the hooks 15 are retained in the best relation when the door is opened so that as it is closed the notched end of the hooks 15 will be in proper position to engage the underside of the body 3 at its inner edge 14, thus securely and automatically locking the door which can then only be opened from the inside of the building.

A shield 18 having its one edge rolled into a tubeiorthe pivot rod 19 maybe madea part of the coal chute, if desired. hen the door is opened to its full extent the shield 18 can be raised by hand to a verticalposition so as to protect the siding of the building. The pivot rod 19 has end bearing in the sides of the body 3 and the shield 18 isheld in proper relation to the sides 10 by means of spacing tubes 22 placed on the ,pivot rod 1 9,a sShown in Fig. 3. Theshield 18 is held in its raised position by a spring catch 21 secured to the underside ofthe upper angle 2 about midway of its length. This catch passes through ahole20,aslshown iniFig. 2. If desired pins 23, shown in dotted lines of Fig.8, may be placed at the outer ,end of the ba-rs 12. Such pins will engage the shield 18 near its pivotalcenten before the door. is fully openedand on-the completion of the door movement the shield will be automatically raised by. the pins and lowered nsthe door is closed.

"From the description andidrawing it will be seen that my coal chuteis intensely pi actica l'in every respect, being planned on strictly.engineering lines the invention is exemplified in a complete andipractical form. 'It has few parts and is extremely simple to construct, installand operate.

IIVhat I claim is:

1. In coal chutes, a frame having an opening therethrough, a sheet steel body secured to the frame, projecting flanges formed on the frame, positioning and retaining members secured tothe sides .of the body adapted to engage the inner face of avbuilding-wall in cooperation with the projectin'g flange of the frame as the latter. engages .the outer face of said Wa l, a door pivot-ed tothe frame, stops on the. frame, sides secured to the door, and projections to said sides adapted to engage the stops of the frame so as to limit the movement of the door in one direction, said stops also limiting thenioyement of the door in the opposite direction.

. 2. In coal chutes, a frame having an opening therethrough, sheet steel body secured .to theframe, projecting flanges formed on the frame, and positioning and retaining. 1n embers secured to, the sides of the body adapted to engage the inner face of a buildingwail in cooperation with the projecting flange of the frameas the latter engages the outer face of said Wall.

3. In coal chutes, frame having an in adapted ectmgflanges of the frame as the latter engage the outer face of said wall a sheet meta door having one edge thereof throughout its length .rolled into a tubular form, and a pivot rod placed within the door tube theends of said rod having hearing in the frame near the-lower edge of its opening in bothsidesthereof. i

4. In coal chutes, a suitable frame, a sheet metal body secured thereto having sides, top and bottom and an openingtherethrouglna sheet metal ,door pivoted to the frame at its lower edge, projecting sides vto the door, and one or more gravity hooks pivoted to .said sides near the outer end .theref, said hooks having notches formed therein, the notches being adapted to automatically engage the inside edge of the bot- ,tom of the body to thereby automatically hold the door closed.

In ,coal chutes, a sheet metal door, flanged reinforcements aong the top and near the bottom edges" thereof, and an integrally formed tubular termination on the lower edge of the door length.

6. In coal chutes, a suitable frame having an opening therethrough, inwardly projecting flanges of the frame, a hinged door adapted to abut said flanges ,on one side thereof, aspring catch on the other side of the flange, a sheet metal body secured to the frame, a shield having an opening there to cooperate, with said catch, and means for pivoting the shield to the body.

7. In coal chutes, a suitable frame having an opening therethrough, a sheet metal body secured to the frame, a shield pivoted to said bodyadjacent the upper edge of the opening, a door pivoted to the body adjacent the lower edge of the opening, projecting sides to the door, and cooperating means between the inner end of the projecting sides and the shield adapted to automat cally raise the shield when the door is lowered and also automatically lower the shield in advance of the closing of the door,

In testimony whereof I my signa= ture.
